+description: |
+  This binding describes a physical power output supplied by a
+  regulator providing efuse functionality (manual on/off control, and
+  auto-shutoff if current, voltage, or thermal limits are exceeded).
+
+  These may be found on systems such as "smart" network PDUs, and
+  typically supply power to devices entirely separate from the system
+  described by the device-tree by way of an external connector such as
+  an Open19 power cable:

+    description:
+      phandle to the regulator providing power for the efuse
+
+  error-flags-cache-ttl-ms:
+    description:
+      The number of milliseconds the vout-supply regulator's error
+      flags should be cached before re-fetching them.
